1、Controlled release fertilizer: A review on developments, applications

As a solution, controlled release fertilizers (CRFs) are discovered where nutrients can be released in a timely and gradually manner, which attempt to coincide and match with the specific nutrient demand during plant growth.

2、HS1255/HS1255: Controlled

To deal with these challenges, the global fertilizer industry has been working to develop new fertilizers called controlled-release fertilizers (CRFs) and slow-release fertilizers (SRFs).

3、The Difference Between Blended Fertilizer, Controlled Release

Many people are not sure what the difference between blended fertilizer, controlled release fertilizer, compound fertilizer is? Today we will do the actual detailed introduction!

4、The difference between controlled

Controlled-release fertilizer and compound fertilizer are two commonly used fertilizers in agricultural production. They differ in composition, production process, fertilizer efficiency...

5、Controlled

ertilizers are generally coated products. Slow-release fertilizers are noncoated products in which the nutrient release is uncontrolled but slow; these are mainly urea-aldehyde reaction products but also include other slowly soluble products such as fertilizer .

Slow and controlled

Controlled-release fertilizers refer to coated fertilizers or to matrices. Coated fertilizers are coated either with a polymer or with an inorganic materials, such as sulfur. Using the matrices technique, the matrix is dispersed within the fertilizer and slows down its dissolution.

Understanding Plant Nutrition: Controlled

In this article, we will discuss how CRF and SRF influence pH and nutrition management. CRFs are primarily water-soluble fertilizer salts or blended fertilizer substrates containing N-P-K or N-P-K plus micronutrients covered in a membrane that limits the solubility of the fertilizer.

Characteristics and types of slow

When compared with conventional fertilizers, controlled nutrient release is thought to be an effective strategy to fulfill the nutrient demand of crops throughout the growth period....

What is Controlled Release Fertilizer? Benefits & Types Explained

Controlled Release Fertilizer (CRF) is a type of advanced fertilizer that releases nutrients at a controlled rate, aligning with the nutritional needs of plants throughout their growth cycle.

What is the difference between controlled release fertilizer, slow

Broadly speaking, both controlled-release fertilizers and slow-release fertilizers are a type of compound fertilizer, and are three-element fertilizers of nitrogen, phosphorus and potassium.

Controlled-release fertilizers (CRF) and compound fertilizers are two common types of fertilizers, but they differ significantly in composition, function, and usage. Below is a detailed comparison of these two types of fertilizers.

1. Composition and Components

• Controlled-Release Fertilizer (CRF): CRF typically contains chemicals with slow- or controlled-release properties, which can gradually release nutrients into the soil over an extended period for plant absorption. The main components of CRF include polymers, trace elements, and other substances that remain soluble in water for a long time. These nutrients are absorbed by plant roots and utilized by the plants. The design of CRF makes it more convenient to use and reduces environmental pollution caused by excessive fertilization in one application.

• Compound Fertilizer: Compound fertilizer contains multiple essential nutrients, such as nitrogen (N), phosphorus (P), and potassium (K). Its composition is relatively simple but provides comprehensive nutrition for plant growth. Compound fertilizers are easy to apply and can be used in appropriate amounts based on the plant’s growth needs.

2. Functions and Effects

• Controlled-Release Fertilizer (CRF): The key advantage of CRF lies in its slow-release properties, which help avoid nutrient loss and environmental pollution caused by over-fertilization. Additionally, CRF can adjust nutrient release rates according to plant growth stages and soil conditions, precisely meeting plant demands. CRF plays a positive role in improving crop yield and quality, reducing chemical fertilizer usage, and protecting the environment.

• Compound Fertilizer: The strength of compound fertilizer is its comprehensive nutrient content, which meets the diverse nutritional needs of plants during growth. It is easy to use, making it accessible for farmers. due to its uniform composition, it may not address the specific needs of certain plants or crops. Long-term use of compound fertilizers can lead to accumulation of certain nutrients in the soil, potentially harming soil health.

3. Usage and Precautions

• Controlled-Release Fertilizer (CRF): The application of CRF should be adjusted based on plant growth stages and soil conditions. Generally, CRF requires less frequent application. When using CRF, it is important to control the dosage to avoid nutrient runoff and environmental pollution.

• Compound Fertilizer: Compound fertilizer is straightforward to apply and can be used in appropriate amounts according to plant needs. When using compound fertilizer, it is advisable to mix it with other fertilizers to prevent nutrient antagonism. Additionally, monitor plant growth and adjust fertilization rates promptly.

Both controlled-release fertilizers and compound fertilizers have their pros and cons. CRF excels in its slow-release properties, minimizing environmental impact and enhancing crop quality, while compound fertilizer provides balanced nutrition for plants. The choice between them depends on specific needs and circumstances.
